Jana Kramer has her hands full as a mom-to-be — she's buying clothes, designing a nursery (with Restoration Hardware everything — swoon), and preparing to walk her first red carpet as a pregnant lady in one week's time!

On gearing up for the 49th Annual CMA Awards on Wednesday, Nov. 4, Kramer, 31, tells Us Weekly, "I'm excited! The same people that made my wedding dress [Galia Lahav] are custom-making me a dress for the red carpet. Every month I'm sending them new measurements, because my boobs are not the size they were when I got married. I was an A, and now, I'm like a D, so they're growing!"

Echoing pregnant Kim Kardashian's sartorial concerns of late, the country singer, who married football player Mike Caussin this past May, confesses, "I'm a little nervous, because I don’t want to look like an Oompa Loompa, you know? But that's why I'm going to show it off — I'm going tight with a low back."

As it turns out, her fitted pregnancy style is inspired by another fabulously dressed A-lister: Blake Lively. "I love Blake's stuff," the Colgate spokeswoman tells Us. "I loved that tight, pale yellow [Gucci] dress she wore. Oh my gosh, gorgeous! That dress is kind of the same thing I'm going for [at the CMAs]. I just want to show the bump off."
